Java is all jacked up...

First off... This is user specific. The other user on my machine works fine. But Limewire, azures, speed tests on dslreports.com... All of them do not work. I just get a blank page. Or even just a red X sometimes.
Whats the deal... Any one have any ideas?
I have reinstalled Java from apple.com.

I fixed it...
Go to Macintosh Hd/Users/your user/library/ and rename the Caches folder to Caches.old
then...
Go to Macintosh Hd/Users/your user/library/ and rename the Preferences folder to Preferences.old
This will fix the issue, but it will also ditch all of your settings. You can go back into the preferences folder and grab some of your preferences back, the put them in the new preferences folder.

[Java and all else] How do you document DB design?

Hello,
Although most of the technical choices are explicit in SQL (UniqueKey & ForeignKey constraints, indexes,...), the semantics of the data columns and their constraints seem better served as plain human-readable comments ("ID column: identifies the plane copy; 6 figures are enough as we don't expect to sell more than 1 million planes in a foreseeable future...").
In my current system, (EJB-based, but the DB schema is not created by the JPA-compliant ORM, but via SQL scripts), I see the following ways to write and maintain this documentation:
- SQL comments in the schema creation and patch scripts
- Javadoc comments in the Java source of the Entity classes.
- UML notes in UML diagrams(1)
- external "Architecture and design" document.
All 4 of them are used, sometimes inconsistently, for various parts of the design choices; I mean, the docs do not contradict themselves (not yet, but it's a mere question of time), but some tables are commented in SQL scripts, others are in design docs, and the details for some columns are in entity javadocs. Although each developer may find it handier to "write" the doc via his preferred medium, it becomes increasingly difficult to "maintain" theoverall documentation.
Our current situation is that most of the project team members are Java developers, so it would probably be better accepted and served if we standardized that we document DB tables and columns in Java source, but I am worried that:
- someone else pouring over our DB (ex: DBA helping us to optimize things, or other team developping a data-mining tool to leverage the historical data in DB) may not be as comfortable with Java
- this may not cover all design choices of the DB schema:
- - - - first, although that is the case currently, in the future there might not be a 100% 1-1 mapping between e.g. each entity class and a DB table. Maybe some columns will not need to be mapped anymore,...
- - - - second, I fear some DB constructs are not amenable to Java counterparts; no accurate idea there, I'm not an SQL nor JPA expert, but I presume Indexes, table partitioning, tablespaces, for example (yes, the DBMS is Oracle :o) are not taken into account in JPA mapping.
And if we document those choices at the SQL level (my preferred idea so far), this will gradually make the javadocs in the entities obsolete, or removed altogether, and that will make future maintenance of the Java source risky.
How do you document your DB design in general?
Do you have specific advices for my case?
Thanks in advance,
J.

Thank you again.
A couple more questions:
2. Table, and proc dictionary maintained as one or more text files. Those files and schema are all in source control.Do you mean, a proprietary text format (a la tabledesign.txt), or +.sql+ source files? Again, you seem to suggest the scehma info is present in two locations.I didn't say two locations unless you meant files. Then yes.Yes I meant two files. I trust the team to get the doc file lagging a few revisions behind the SQL file, and to correct that I would have to include one more step in the review process (e.g. "review CM actions to check that the doc file is updated consistently with the SQL source").
The tool I wrote would throw errors if the comment file didn't match the schema. And if comments were not provided. That of course doesn't stop someone from documenting a table with "a table".
You can of course keep the addtional info as special comments in the SQL, but when I did this, and even in retrospect, it seems better and perhaps easier to keep them seperate. I have done special comments in SQL before and it seems a bit of a kluge but you do have the single source. But in that case I was the only one maintaining it too.What do you mean by "special"?For code generation I have a schema file with the following (pseudo sql.)
    create mytable
       mytable_id int,
       column_foo varchar(10);
       column_fum varchar(20)
        -- Query: for_a_query (column_foo, column_fum)
    )The generator consumes the schema and generates the standard CRUD which would include a query based on the primary key.
The above comment is used to provide an additional query where the proc is named 'for_a_query' (munged with table name) and takes two parameters (column_foo, column_fum) whose type/name matches those of the table.
If we don't try to generate a browseable HTML out of the schema (although the idea is appealing, I don't have the resource to make such a tool), do you see anything kludgy in maintaining SQL comments interpersed within DDL code?
Of course that is doable.

Can't run java at all

Hello!
I have a 600 megahertz Intel Pentium III machine running Windows 98 SE. I use the following browsers: Netscape 4.79, 6.2 and internet explorer 6.
I was able to run java applications on my computer very well. I purchased a program to make web buttons. The program worked very well for a time and it just stop working after a while. I contacted them and was told to upgrade my jvm machine by downloading the newest msjavx86.exe from microsoft and installing it to see if it will solve my problems. It did not work.
I get this message everytime that I try to use the program:
"Can't find the file "BtnAuthor.class" can't execute class "
I'm unable to run any java and all I see are grey boxes with codes. Any idea of what could be wrong or how to fix this problem.
Thanks for your time at reading this
Ann :-)

Well, I'm quite unfamiliar with this. I just opened the java console on netscape 4.79 (my favorite) and I got the following:
Netscape Communications Corporation -- Java 1.1.5
Type '?' for options.
Symantec Java! ByteCode Compiler Version 210.065
Copyright (C) 1996-97 Symantec Corporation
Then I pressed the "?" and got the following:
Netscape Communications Corporation -- Java 1.1.5
Type '?' for options.
Symantec Java! ByteCode Compiler Version 210.065
Copyright (C) 1996-97 Symantec Corporation
Netscape Java Console Commands:

d: dump applet context state to console
f: finalize objects on finalization queue
g: garbage collect
h: print this help message
l: capture all classes loaded by an applet to a directory
m: print current memory use to console
q: hide console
s: dump memory summary to "memory.out"
t: dump thread info to "memory.out"
x: dump memory to "memory.out"
X: dump memory (detailed) to "memory.out"
0-9: set applet debug level to <n>
I'm not sure if I should explore any of this options at this time. I have no idea of how to write a simple java on my own. The button program was supposed to do the writing and I was just supposed to paste it it in the html.
Thanks for helping me! :-)

I have mac os x 10.6.8. The system preferences doesn't show java at all. How can I install java please?

Hi!
I have mac os x 10.6.8. The system preferences doesn't show java at all. How can I install java please?

Don't change your story now. You did not say through Apple, you first gave a link to this site,
http://www.java.com/en/download/apple.jsp
You said, "Go there and download the latest version of Java"
that plainly says,
"Mac OS X Version 10.6 and below
Use Software Update available on the Apple menu to check that you have the most up-to-date version of Java 6 for your Mac."
This corroborates me saying that Java for Mac OS 10.6 is done through Software Update, no where else.
If any Mac OS 10.6 user does not have Java on their Mac, they get it from Apple just as the link you provided shows it is from Apple. Not Oracle. You have provided the evidence that plainly contradicts yourself.
This is your second link that is to Apple.
http://support.apple.com/kb/DL1573
Just to go over this again. Software Update not only updates Java to the latest, but if Java does not exist at all, SU will install it from scratch. And in doing so will be the latest version.
Providing a link to Oracle's site is useless information that does not get Java installed on a Mac running 10.6.

Why is the newest version of Firefox not compatible with Java ? All my java extensions are disabled !

I can't be entirely certain of the origin of this issue, but I've tried everything I can think of and the only thing I can nail down is that Firefox 6.0.1 is incompatible with Java. All of my extensions have been disabled without the option of even trying to enable them.
Now for the ACTUAL problem...this affect my Google/GMAIL experience and I use GMAIL for my business! The calendar used to display various mailboxes with different colours to identify different types of individuals and the Google Menu Bar on their homepage is not black, like it should be, it is TRANSPARENT with blue lettering. I can read the menu bar just fine, but the GMAIL thing is kind of important to my business!
I've tried the GMAIL forums to no avail...I've tried to uninstall Java [it wouldn't...just crashed and said there was an error...]. I even re-installed Java, but nothing changed!
I have also tried other browsers and they do the same thing, so I can't just pin it on Firefox, but I am hoping that someone here will have a good, working solution for me.
Thanks,
Dave

OK, I'll try removing all of the extensions but that doesn't explain why my GMAIL and various other JAVA related [I'm assuming] things are not displaying properly. I even went as far as to replace my video card and download the most up to date drivers...still no change, but I will try removing all of the disabled extensions.
Thanks and if anyone has any other ideas I'd love to hear them

Try exporting *just* the audio as an AIFF, bring that back in, and export with that single .aiff file.

Brand new OS X Mountain Lion starts in grey screen login window doesn't know me verify passwords all jacked up says to get external hard drive recovery so I have to spend more moneyon my brand new computer or can I fix and safe boot

brand new OS X Mountain Lion Bought in November 2012 starts in grey screen login window doesn't know me, went to utility dIsk ,verify passwords all jacked up, I Engaged repair passwords then press verified Macintosh HD it said Macintosh HD is OK but repair disk button was still lit up and wanted me to make a recovery disk external hard drive and such,please tell me I can fix in safe boot..

The repair button is always clickable when you are on your Recovery partition, it's nothing to worry about. Do this instead.
Then start in single user mode (Command-S)
Type fsck -fy to check your disk first (it wont let you start working on a disk until you have checked it)
Then type mount -uw / (dont forget the slash) to mount your Macintosh HDD
Then type passwd username with username being the username of your admin account
It will make you type the new password twice afterwards. From then you can boot into OSX as normal and use that account to fix the rest of your passwords.

[Java and all else] Requirements tracking, testing, and versioning

Hello,
as a semi-experimental subject, I am considering managing requirements and test documents in the same version control system as the code.
For some reasons, this versioning policy doesn't seem mainstream, so I'd like to have your opinion on that.
+N.B.: the prefix "java and all else" refers to the fact that I'm using this area to post a message that is related not only to Java but also to other topics (people, processes, tools,...) that help program in Java - so this post is not really off-topic either. For the record, I filed a suggestion to open a dedicated forums to discuss topics like that, although it hasn't received enthusiastic support so far :o(...+
Here is how I had imagined to proceed:
- requirements document gets edited and stored as text in the VCS
- test plan (basically a matrix of which tests cover which requirements) goes into the VCS as well, text or binary
- test instructions (detailed steps, actions, expected results) are stored as text in the VCS
- test results - I do'nt know yet, but I planned to store them as text (lists of testId=result) in the VCS (I'm not sure indeed, that those would go into the VCS)
The advantage of versioning those as text is that all VCS clients support easy-as-a-click history browsing and diff capabilities.
Diffs and logs are useful to trace when and why a requirement has appeared, evolved, obsolated,... Especially in long-lived systems whose maintenance crew rarely embeds "historical" pioneers who developed the original systems.
My questions:
1) Is it good practice to version such docs in the same repository as the code?
I've never seen this done.
- In half of the shops I've been these docs are not really versioned (the PM considered it enough that the latest applicable version of the docs was available)
- The other half has used versioning systems ranging from ad-hoc (shared folder acting as repository of all versions) to "document management systems". I found such tools to be developer-unfriendly (poor diff capability, poor text searching), and developers to be office-document-reluctant (mostly because of the shortcomings of the doc format and doc management systems).
- The third half <wink to aficionados of French cinema> used dedicated softwares (Test Director, RQM,...) to manage requiremetns, test plans, test cases, test results,... The drawback is that the developers were hardly involved in using such tools, and even when they were, were not trained to use the administrative and metadata capabilities (who modified the test steps, when and why?).
On the contrary, developers would easily and gladly browse histiry, check diffs, etc... on text documents versioned using their daily-used source control system.
2) Are there "standard", preferrably text-based, formats, for the documents listed above?
Each and every organization I've seen had its own format, but most items have equivalents in all organizations, even if disguised under different terminologies. I have no formal education or training in quality assurance, but I guess some ISO or CMM norms define those recurring items, and I expect some abstract XML format might exist
3) Are there tools already that cover edition and exploitation of such formats, or why not, of the versioning of such formats (naive example, graphing the pass rate of tests over time)?
A pet project of mine is to develop and open-source some Swing UI to do this, but existing tools would save me the trouble.
I'm looking forward to reading about your own experience.
Best regards,
Jerome.

Fixed link.

I don't have data on comparative bug rates because we did not do studies focused on that. This stuff was mostly driven by convenience #) considerations.
Subjectively, yes it seemed to have lower bug rate compared to maintaining documents in, say, pdf format (like our doc writers did with User/Dev guides). BTW doc writers are another kind of guys who dislike plain text.
As for using test results history the way you describe - agree, that makes some sense. Now that you mention it I recall using it myself that way, in one of the projects where testers managed to establish really convenient way to assess test execution history. After I figured how easy it was, I began using it. Quite helpful indeed.
Regarding "tool or format that mapped tests to specific requirements" in your original post - did you consider Polarion? IIRC it supports mapping requirements to test descriptions. Telelogic DOORS are maybe also capable of that but I am not completely certain.
#) convenience -- BTW we maintained test descriptions not in plain text but in simple HTML (you know few tags one can use in javadocs). With limited line length, it is almost as VCS friendly as plain text, even with tables:
<!DOCTYPE "stuff to make HTML validator happy">
<html><title>test description</title>
<body>
<table>
<tr>
    <td>test id</td>
    <td>synchronized.10988343</td>

<tr>
    <td>instructions</td>
    <td>

        <li>sacrifice a goat

How to clone front jack to all jacks

( hmmm it seems ok now.... but is there any change to get the same for all jacks (not mic but the other ones). I can't understand why it can't just adjust every jack independently. The freaking realtec is doing it without any problems..... you can even adjust the mic jack as [email protected]

Do java supports all unicode characters including telugu..??

Hello to Everybody..!
Iam rather new to java technologies and I want to know whether java supports telugu language and if it supports it ,how can we implement it? and is there any system requirements for it.?
Please Kindly consider this query and Thankks in advance.

Yes, Java supports all Unicode characters. If you want to know more about Unicode, have a look at its website:
http://www.unicode.org/
Telugu characters are in their code charts here:
http://www.unicode.org/charts/PDF/U0C00.pdf
You don't have to "implement" anything. System requirements would include a font that can render those characters. I don't know about keyboards.

Upgraded to version 5, now no Java at all

Last week, like a dummy, I upgraded to version 5 not knowing it was only supported on WIN98 SE. I'm running WIN98. As a result, I cannot open any applets. I uninstalled version 5, but also uninstalled my previous version ( I told you I was a dummy). I've tried reinstalling 1.4.2_07 and _09 with no luck. My question is, which version do I need to get Java RE up and running again?

I did that........still no joy. I'm wondering if I have to go all the way back to the start (1.4.1) and try that. I've been at this a week now, with no solution. I've tried going back to the MSJVM and that was no good either. I really am on the verge of swapping this machine for the one in my digital darkroom.

USB data manipulation from Java to all OS

Tracy,
<quote>â¦ only on row #40, the internet connection is lost. The only way the user can tell what happened is to look at the entire screen and reverify ALL the data in order to tell what got saved/resaved and what didn't</quote>
That would be "the only way" if the Java programmers had decided to totally bury the error â¦ what should happen here is the end-user should get a proper error message â¦ no need to re-verify at this point since all bets are off (in fact, nothing shouldâve been changed in the database).
Nonetheless, your concerns regarding the chosen approach are valid â¦ making multiple calls to the database after a Save makes controlling a business transaction rather complex (in an n-tier system) â¦ they should make one call only to the database passing in all the data to be saved â¦ one database transaction â¦ either all changes get applied or none.
The fact that lots of data may need to be passed in for one Save is of no relevance â¦ if you have to carry 500Kb of data for that screen then, well, you have to do it â¦ 1 bucket of 500Kb or 50 buckets of 10Kb? â¦ it doesnât really matter as far as the actual transport part is concerned.
As already answered, one can pass complex types in pl/sql â¦ so one database call per Save would be my first random thought. There are lots of suspect things in here â¦ some things you didnât mentioned at all â¦ like how is concurrency addressed? â¦ have you/they implemented some sort of optimistic locking mechanism? Of course the architecture of your system wonât be solved in a forum â¦ so, finding a good system/data/Oracle architect on site for the project would be my second random thought.
PS. One last random thought â¦ fight off that idea of packing and sending large strings (XML or not) â¦ if the data is structured then contemplate XML for no more than few seconds.

Java using all available cpu

I am having an issue with my weblog server. Whenever someone try's to get to my weblog server the java process takes up all the processor. And I cannot access my weblogs.

Just wondering if you ever solved your problem? When I have WO running my
java process is taking about 90-100% CPU.
